Yes, it really will be 10 years since “Seinfeld” left the air and “Sex and the City” came on. Yes, it really will be 30 years since the Bee Gees ruled the universe. And yes, we guarantee that you’ll ask, “has it really been that long?” at least once when you check out our list of some pop-culture anniversaries we’ll be observing in 2008:

50th (1958)

Feb. 3: “Great Balls of Fire”

Goodness, gracious, has it been a half-century since Jerry Lee Lewis proclaimed his burning desire in this hit song? (His career would suffer a major setback later that year when it was revealed he married – his 13-year-old cousin.)

March 24: Elvis is inducted into the Army

A crew cut replaces the pompadour and sideburns, and across America, teenage girls’ hearts are torn asunder.

40th (1968)

Jan. 22: “Rowan & Martin’s Laugh-In”

Fast-paced (for the time) laugh-a-minute hour that revolutionized the sketch/variety show (for the time). Some say presidential candidate Richard Nixon’s September cameo (“Sock it to me?”) helped give him the edge in his neck-and-neck race with Hubert Humphrey.

March 16: Otis Redding’s “(Sittin’ on) the Dock of the Bay.”

This wistful posthumous hit, recorded three days before his death in a December 1967 plane crash, was the soul singer’s legacy.

Nov. 25: “The White Album”

The double LP, officially titled “The Beatles” – packed with such great songs as “Back in the USSR,” “Happiness Is a Warm Gun” and “Birthday” – goes on to become the bestselling Fab Four album.

30th (1978)

Jan. 1: The Bee Gees dominate the universe

Not even the Beatles ruled the charts like this: Thanks largely to the “Saturday Night Fever” soundtrack, during an eight-month period beginning in the Christmas season of 1977, the brothers Gibb wrote six songs that hit No. 1 for 25 of 32 weeks.

July 28: “National Lampoon’s Animal House”

Double secret probation . . . “Fat, drunk and stupid is no way to go through life.” . . . “Toga! Toga! Toga!” What more can we say?

25th (1983)

Feb. 28: “MASH” finale

“Goodbye, Farewell and Amen” is still the most-watched episode in TV history, with an estimated 106 million viewers tuning in.

March 5: Michael Jackson

“Thriller” may have been released the previous year, but in ’83 the album landed seven songs in the top 10 (including “Billie Jean,” which topped the charts for seven weeks).

20th (1988)

April 19: Public Enemy’s “It Takes a Nation of Millions to Hold Us Back”

One of the greatest hip-hop albums by the greatest hip-hop group from Long Island.

10th (1998)

Jan. 20: “Dawson’s Creek”

Every generation needs a teen-angst drama of its own. Those too young for “90210” embraced this sex-obsessed WB drama that launched the careers of Katie Holmes and Michelle Williams.

May 14: “Seinfeld” finale

The fabled show about “nothing” went out with a one-hour episode in which the four pals end up jailed for violating a small town’s good Samaritan law. Their crime: They did “nothing” to stop a carjacking.

In a friend's dining room in central Los Angeles, 27 hours before she will announce she's running for president of the United States, I ask self-help author and motivational speaker Marianne Williamson to perform a miracle. Until a few weeks ago, I didn't know Williamson was planning to join the Democratic presidential primary class of 2020.
